Patent CA-2022136-C (CA)
Inventor: TENCZA STEPHEN JOHN
IPC: F01D25/24
Filed: 1990-07-27
Granted: 2001-02-20
Abstract: The method of the present invention uses a combination of gap measurement methods to map the gap in a joint in a high pressure vessel such as a steam turbine or steam valve. An exposed and supported surface is hydraulically balanced allowing any twisting of the surface to be removed. The map is then created using a blue contact method, feeler gages, deformable gap measuring medium and laser profiling for both surfaces of the joint. A restoration plan is produced using the map which minimizes the restoration work and produces matching joint surfaces. The joint surfaces are welded and/or machined and finally finished in accordance with the plan. A laser can be used to guide or reference the machine tool. Matching joint surfaces, especially if relatively flat, provide a better high pressure seal than relatively flat surfaces that do not match while relatively flat surfaces that do match produce an even better seal.

Inventor: HAWARI JALAL A
IPC: A62D3/00
Filed: 1990-09-28
Granted: 1999-04-06
Abstract: A process for the reductive dehalogenation of halogenated aromatics.   The process comprises reacting halogenated  aromatics  with  sodium  or  calcium  in  the presence  of  a  lower  alcohol  selected  from  the  group comprising methanol, ethanol or isopropanol and mixtures thereof in order to convert the halogenated aromatics to hydrogenated aromatics.   The halogenated aromatics are preferably reacted with sodium in the presence of methanol under reaction conditions whereby said sodium is in molten form.    The  preferred  starting  sodium/methanol/halogen molar ratio ranges from 30-40/15-20/1.   The process is particularly useful  for  dechlorinating  polychlorinated biphenyls found in electrical transformer oil.

Title: Motor fuels of enhanced properties
Inventor: HANLON JOHN VINCENT
IPC: C10L1/30
Filed: 1991-06-26
Granted: 2002-04-02
Abstract: Environmentally-friendly fuels are provided comprising a gasoline fuel composition having a Reid vapor pressure (ASTM test method D-323) of 8.5 psi (58.6 kPa) or less, and preferably 8.0 psi (55.2 kPa) or less, containing up to 1/32 gram of manganese per gallon (0.008 g/liter) as at least one fuel-soluble cyclopentadienyl manganese tricarbonyl compound. Such motor fuels have improved octane quality as compared to the clear base fuel, and thus do not require the use of increased proportions of aromatics in the fuel. In addition, the motor fuels contribute to clean air by resulting in less evaporation into the atmosphere during such operations as storage and dispensing to vehicles and by resulting during engine operation in reduced emission of carbon monoxide (CO) and oxides of nitrogen (NO x) while having little effect on the level of tailpipe hydrocarbon emissions. The fuels exhibit virtually no adverse effect upon exhaust gas catalysts of the type commonly used in present-day vehicles. Because the base fuels can contain reduced volumes of aromatics, the antiknock response of the fuels to the addition of the cyclopentadienyl manganese tricarbonyl compounds remains high.

Abstract: In the manufacture of mozzarella cheese, aging can be dispensed with if the process is controlled to yield a combined moisture and wet milkfat content of at least about 70 weight percent, and the cheese will provide acceptable bake performance under typical cooking conditions used in the pizza industry today. Within about 48 hours after brining, the cheese should either be used or frozen. this discovery saves at least seven days of aging and permits the use of a continuous process of making mozzarella, which, from pasteurization to loading of the frozen product on the truck, can be performed in as little time as eight hours. In the continuous process, the hot stretched cheese from the kneading machine is extruded directly into cold brine. After the cheese has cooled sufficiently, it can be comminuted and frozen by independent quick freezing, preferably in a fluidized bed freezer. Salt preferably is mixed into the cheese during the kneading step.

Abstract: Interference in a high speed receive signal is effectively detected in a TDMA communications system wherein a plurality of time slots is provided within a TDMA frame.  A comparator is arranged to receive a first signal indicative of receive signal strength and a reference level signal.  The comparator compares the magnitudes of the two signals applied thereto and outputs a comparison result signal.  A delay circuit is supplied with a second signal indicative of a time slot which is not in use and which delays the second signal by a predetermined time using a clock which is synchronized with the time slots of the TDMA frame.  A gate circuit, preceded by the comparator and the delay circuit, is supplied with the outputs of the comparator and the delay circuit.  The gate circuit outputs a third signal which changes a logic level in the event that the strength of the first signal exceeds that of the reference level signal during the time slot which is not in use.

Title: Air separation method for supplying gaseous oxygen in accordance with a variable demand pattern
Inventor: MOSTELLO ROBERT A
IPC: F25J3/04
Filed: 1992-04-28
Granted: 1995-06-27
Abstract: An air separation method for supplying gaseous oxygen to meet  the requirements  of  a  variable  demand  cycle.    In accordance with present invention, air is rectified by a double column  low  temperature  rectification  process  to  produce  a nitrogen rich vapor and liquid oxygen in high and low pressure columns.  The nitrogen rich vapor and the  liquid oxygen are withdrawn   from   the   high   and   low   pressure   columns, respectively.   The  nitrogen rich vapor  is  partially  heated within  a  main  heat  exchanger  of  the  process  and  is then, turboexpanded to create plant refrigeration.  When a demand for gaseous  oxygen exists,  a product  stream formed of withdrawn liquid oxygen is pumped to delivery pressure and the nitrogen rich vapor  is diverted within the main heat exchanger  from being  partially  heated  and  expanded  and  is fully  heated, compressed and then condensed against vaporizing the product stream to form the gaseous oxygen.  The condensed nitrogen is then flashed into a flash tank.  The flash vapor is added to the diverted nitrogen rich vapor to increase the vaporization rate of  gaseous oxygen.   The  resultant  liquid is introduced into the low pressure column as  reflux to allow the withdrawal of the liquid oxygen.  Any excess amounts of the liquid oxygen and condensed nitrogen not immediately used are stored.
